Image description: USGS scientists examine thermal imagery of wolves for assessing impacts of sarcoptic mange on the survival, reproduction and social behavior of this species in Yellowstone National Park.
Sarcoptic mange is a highly contagious canine skin disease, caused by mites that burrow into the skin causing infections, hair loss, severe irritation and an insatiable desire to scratch. The resulting hair loss and depressed vigor of an infected animal leaves them vulnerable to hypothermia, malnutrition and dehydration, which can eventually lead to death.
Note the bright red patch on the wolf’s hindquarters in this thermal image of a captive wolf at the Grizzly and Wolf Discovery Center in West Yellowstone. This is where fur was shaved to replicate the loss of fur associated with sarcoptic mange. The fur will eventually grow back. All research animals are handled by following the specific requirements of USGS Animal Care and Use policies.

There’s a new addition to the neighborhood!
NASA researchers have discovered an object whose orbit is beyond the known edge of our solar system. The possible dwarf planet’s orbit stretches farther than Pluto and beyond Sedna, which was previously believed to be farthest object in the solar system.
This discovery shows scientists that the outer-limits of the solar system are not the “vast wasteland” they were once thought to be, and there is much more out there to explore.

The 2008 summer expedition was the first part of a larger multi-year project to research and document a number of historically significant shipwrecks tragically lost during WWII. The project is dedicated to raising awareness of the war that was fought so close to the American coastline and to preserving our nation’s maritime history.

Hugh Turvey calls one of his earliest images Femme Fatale. Using an x-ray, he scanned his wife’s foot in a dangerously high stiletto.
“I think we all understand that your foot is going through quite a lot when it is in a stiletto, but to actually physically see it and to see the angle of the bones,” says the British artist. He completes his thought, I imagine, with a shiver. “Not only do you have this distorted foot, but you have these small nails that were in the actual construction of the shoe. It just looked like a torture device.”
